VizieR Online Data Catalog: Herschel-PACS legacy of low-mass protostars (Karska+, 2018)

The low-mass embedded protostars analyzed here were initially observed as part of the WISH (van Dishoeck+ 2011PASP..123..138V) and "Dust, Ice, and Gas In Time" (DIGIT, Green+ 2013ApJ...770..123G) surveys, which comprised 18 and 29 protostars targeted with PACS, respectively, including eight overlap sources. This sample was subsequently expanded by the WILL survey (Mottram+ 2017A&A...600A..99M), where a further 49 sources were observed, including 37 Class 0/I objects. Three additional sources were located in the PACS spectral maps of the primary targets, increasing the sample to 90 sources in total (for details, see Table 1).

Single-footprint spectral maps of all sources were obtained with the PACS instrument onboard Herschel. Each map consists of 25 spatial pixels (spaxels) of 9.4"x9.4", arranged in a 5x5 array with a total field of view of ~47"x47". Each spaxel contains a (sub-)spectrum observed in the first (red) or second (blue) order, within the wavelength ranges of 102-210um and 51-105um, respectively.
